Encryption isn’t just a good idea. It should be mandatory practice for anyone who cares at all about security and privacy.
So as a reminder to myself: use Truecrypt more frequently. Even on Ubuntu, it’s insanely easy and will help you sleep better at night. Old documents that need to remain confidential (or perhaps even securely deleted), financial stuff, et cetera… why do you just keep them sitting in the clear on your hard drive?
My next minor project involves GnuPG and then leveling up in Tor, which I already use. I’d like to do so more effectively, in fact, and I have some ideas for a project similar to Tails with some enhancements.
